Along with the CD-RW problem encountered by some players, there are some players, like NAIM, that will not play certain newer copyright protected CD's. These CD's are technically NOT a conventional Redbook standard CD but are sold as such. Only a few players have problems with them, while others play them just fine. Naim actually has issued a revised chip for many of their players that is a plug-in replacement and will allow playing of the copyright protected formatted CD's in question. It cost about $75 for the chip replacement in the case of Naim. I'm not sure what other manufacturers may be doing about this. Another thing we can all thank the audio recording industry for in their continuing fight to protect the intellectual rights of their artists (HAHAHA), not to mention the companies precious MONEY!
